I checked several configuration of the "size_addition" option and it
does not work.
I also sent an email to another of my servers running both Exim and
spamassassin as well.
I got the following, clearly telling DKIM_INVALID :

Jeremy, you told me what I sent to your private email was ok, but on my
side I can not reproduce any recipient (mail-tester.com, gmail.com,
another of my server) where the DKIM signature is valid...
